A wall plate adapter for coupling home network control signals to AC power wiring, where the wall plate adapter includes built-in signaling circuitry. The wall plate adapter includes a plate with a receptacle face with slots that are aligned with slots of an underlying AC receptacle. When prongs of a plug are inserted into the slots of the wall plate adapter, they touch contacts that are located in the slots of the receptacle face. The contacts are, in turn, coupled to the signaling circuitry, which may be located in an enlarged region of the wall plate. The signaling circuitry is only coupled to the AC power when a plug is inserted. The plug may be coupled to a transformer and a network device.

An apparatus and method are provided for a security device for residential and/or commercial use. A first magnetic member has a first magnet with a north and south pole, and a second magnetic member has a second magnet with a south and north pole. Contact between the north pole of the first magnet and south pole of the second magnet, or vice versa, completes an electrical circuit by conducting electricity between the first and second magnets, and a magnetic force between the first and second magnets holds the first and second magnets in contact. The electrical circuit is broken when a force sufficient to overcome the magnetic force is applied to separate the first and second magnets. When contact between the first magnet and second magnet is broken off, such as by opening a door or window, the electrical circuit is broken, and an alarm is triggered.

Pull-apart contact using magnets to complete the circuit

A tamper detection switch is primarily for use in an enclosure of a security system component. The enclosure has a base and a cover that may be repositioned relative to the base. One of the cover and the base holds a conductive magnetic element free to translate within a predetermined range generally perpendicular to the respective cover or base. The other of the cover and the base holds at least two ferrous metal contacts of an open tamper circuit in proximity of a conductive magnetic element. In the closed position the conductive magnetic element bridges the ferrous contacts and closes the tamper circuit. Attempts to tamper with the enclosure separate the ferrous contacts from the conductive magnetic element, opening the tamper circuit and signaling a possible attack.
